CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from Korean Patent Application No. 10-2016-0092792, filed on Jul. 21, 2016, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

BACKGROUND 1. Field

Apparatuses and methods consistent with exemplary embodiments relate to a spectrum measurement technology, and more particularly, to an apparatus and method for acquiring a spectrum based on a vein pattern.

2. Description of Related Art

Diabetes is one of the modern chronic diseases, which is diagnosed when an insulin hormone is not properly secreted from a pancreas, and glucose within blood is not transferred to cells for use as energy and is accumulated in the blood. Diabetes may lead to complications, such as high blood pressure, renal failure, blindness, and the like.

Blood glucose measurement methods may include an invasive method that measures a blood glucose level from a blood sample directly collected from a patient, and a non-invasive method that measures a blood glucose level without drawing blood. The invasive method shows high measurement reliability, while causing pain, inconvenience and a high risk of infection due to use of an injector. Also, the invasive method can incur an economic burden to the patients due to use of consumables, such as strips for measuring body fluid components, disposal syringes, and the like. In the non-invasive method, a variety of optical technologies such as Raman spectroscopy, near infrared spectroscopy, and mid-infrared spectroscopy have been applied.

Meanwhile, in the non-invasive method associated with optical technology, even a slight change in a spectroscope's spectral measurement location may lead to an increase in spectral measurement noise. The increase in spectral measurement noise is a cause of lower measurement reliability of the non-invasive method using optical technology.

FIG. 1 is a block diagram illustrating an exemplary embodiment of a spectrum acquisition apparatus. The spectrum acquisition apparatus 100 may be an apparatus that recognizes a vein pattern and acquires a skin spectrum of a desired area of a human body based on a result of the vein pattern recognition.

The spectrum acquisition apparatus 100 may be realized as a software module or manufactured in the form of a hardware chip to be equipped in an electronic device. In this case, the electronic device may include a mobile phone, a smartphone, a tablet computer, a laptop computer, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation system, a MP3 player, a digital camera, and a wearable device. The wearable device may include devices of a wristwatch type, a wristband type, a ring-type, a belt-type, a necklace type, an ankle band type, a thigh band type, a forearm band type, etc. However, the electronic device and the wearable device are not limited thereto.

Referring to FIG. 1, the spectrum acquisition apparatus 100 may include a spectroscope 110, a vein pattern recognizer 120, and a spectroscope controller 130.

The spectroscope 110 may emit light onto a user's skin, receive light reflected or scattered from the skin, and measure the skin spectrum through spectroscopy of the received light. The spectroscope 110 may include a light source, such as a light emitting diode (LED), a laser diode, etc., and a light detector such as a photodiode, a phototransistor (PTr), a charged coupled device (CCD), etc.

The vein pattern recognizer 120 may recognize a vein pattern of a body area in which the spectroscope 110 is located. For example, the vein pattern recognizer 120 may emit infrared light to the body area in which the spectroscope 110 is located, and recognize a vein pattern of the body area by receiving infrared light reflected or scattered from the body area. Because hemoglobin contained in the blood absorbs infrared light by its nature, the vein pattern recognizer 120 may recognize the veins of an object using such properties of hemoglobin.

The spectroscope controller 130 may control the operation of the spectroscope 110 based on the vein pattern recognition result, and acquire a skin spectrum of a body area of interest. For example, the spectroscope controller 130 may compare the vein pattern recognition result with a stored vein pattern of the body area of interest in order to determine whether the spectroscope 110 is located at the body area of interest, and control the operation of the spectroscope 110 based on the determination so that the skin spectrum of the body area of interest can be acquired.

According to one exemplary embodiment, the spectroscope controller 130 may operate the spectroscope 110 only when the spectroscope 110 is located at a body area of interest, so as to acquire the skin spectrum of the body area. In other words, when the spectroscope 110 is not located at the body area of interest, the spectroscope controller 130 does not activate the spectroscope 110, but activates the spectroscope 110 only when the spectroscope 110 is located at the desired body area, thereby preventing unnecessary power consumption.

According to another exemplary embodiment, in order to obtain the skin spectrum of the body area of interest, the spectroscope controller 130 may select a skin spectrum that is measured when the spectroscope 110 is located at the body area of interest from among a plurality of skin spectra measured by the spectroscope 110.

According to another exemplary embodiment, when the spectroscope 110 is not located at the body area of interest, the spectroscope controller 130 may automatically adjust the location of the spectroscope 110, and operate the spectroscope 110 automatically or according to a user's command so as to acquire the skin spectrum of the body area of interest.
